` claims.

Another object of Amy invention is to provide a screen of the kind indicated which is readily inserted and removed.

A further object of my invention is lto provide a screen which can be used withthe same effect with a number of different openings of the window.

Some embodiments of my invention `are illus- 2O'trated, for the purpose 'of explanation, in the drawing, in which:

Fig. 1 shows a partial perspective view of one embodiment of the screen,

Fig. 2 shows a partial sectional `plan view of the same attached to a window,

Fig. 3 shows a plan view of the screen with the sidemembers tilted down,

Fig. 4 shows an elevation of the same, Fig. 5 shows a plan view of another embodiment of my invention, v Fig. 6 shows a partial plan view to an enlarged scale ofthe same attachedto 'a window,

Fig. 'I shows diagrammatically the arrangement of the screen in a window of the type having a sash mounted in a frame so as. to pivot about an axis at about the middle of the height of said sash, and

Figs. 8 and 9 are detail views.

In the embodiment shown in Figs. 1 to 4, inclusive, the screen comprises a bottom member I and two side members 2, 3 for covering the rectangular opening and the two triangular openings, respectively. The window frame is indicated by 4 and the window sash by 5. The side members 2, 3 of the screen are connected with the bottom member I by means of hinges 6 and 1, respectively.

The screen is secured to the sash 5, for in- 50 stance by means of turnable heads 8 connected to the sash and coacting with elongated holes 9 in a ange I0 on the screen member 2. Said heads 8 are of an elongated shape and rather narrow, so as to pass readily through the holes 55 3 when turned to a corresponding position, whereas they lock the screen to the sash, when turnedA to any other position.

At the inner edge, said side screen member 2. is provided with a flange II projecting in a direction opposite to the ange I0 and serving as 5 an abutment and tightening means between the screen member 2 and the sash. The screen member has, of course, a similar flange, and preferably also the bottom member I is provided with a flange I2 of the same kindand for similar 10` and other purposes.

In order to ensure suiiicient degree of tightness between the screen and the frame also in case the window sash is not opened enough to establish engagement between the frame 4 and the 15 flanges II, I2, cords I3 of rubber or similar material are provided on the outside of the screen members, as indicated in the drawing. `Of course, tightening means for the same` purpose can be arranged also in other ways as, for in- 20' stance, by fastening rubber strips I4 by means of clips or clamping means I5, as indicated in Fig. 9.

rI'he dotted lines in Fig. 4 indicate how the screen can be folded together by moving the side members 2, 3 towards each other. In a window 25 pivoted at about the middle of its height there will form two rectangular and four triangular openings, and the screen will assume the general appearance illustrated diagrammatically in Fig. 7.

vIn the embodiment of my inventionillustrated 30 in Figs. 5 and 6, the screen comprises two units, each of the same general design as the screen' described above. Thus, there is one unit A comprising a bottom member 20 and two side members 2|, 22 connected with the bottom member 35 20 by means of hinges 23 and 24, respectively. Another unit B comprises a bottom member 25 and two side members 26, 21 connected to the bottom member 25 by means of. hinges 28 and 29, respectively. 40

The unit B is somewhat smaller than the unit A so that it can be mounted within said unit A, as shown in Fig. 6. The unit B is detachably secured to the sash 5 in a similar Way as described in connection with the embodiment of Figs. l to 4, inclusive, i. e. by means of a ilange I0 and fastening means 8 for coaction with holes in said flange. At the opposite edge a rubber strip 30 is mounted in a holder 3l.

The other unit A is detachably fastened to either the window frame or the sash at two points 32 and 33 (Fig. 5) only and is thus swingable about said two points. It is provided with two flanges 34 and 35 projecting in opposite directions, as shown in Fig. 6. Cords I3 of rubber or 55 similar material are provided in the same way and for the same purpose as in the embodiment of Figs. 1 and 2.

It should be obvious that, when the window is 5 being opened, the screen unit B is participating movement of said sash 5, the cords I3 thereby. tightening the joint between the unit A and the frame 4, as indicated in Fig. 6. Finally the ange 1 35 engages the frame 4, the two screen units A and B then together covering the entire opening between the frame 4 and sash 5.

Several different modifications of the embodi-` ments described can be made without departing from thescope of the invention. Thus, in some` cases,v it might be advisablejor .necessary to make the bottomparts'of the screen-curved as seen in cross-section instead of straight, as shown E iniFig; -`1. Also in lother respects modications are'feasible and,- therefore, the embodiments described above must not in any way be interpreted as limitations of the scope of the inventioinfbut justas exemplications. f

39:", It is also within the concept of` the present.`

invention to make the bottom members I, 20 and 25 of ,variable width so that the screen canbe used in; windows of different widths. y'This may. be accomplished by making the bottom members 20 :and `25-in two or; more overlapping sections slidably connected toeach other. vOne sectionk of` a bottom member formed of a plurality of sections may be telescopically slidably mounted in asecond adjacent section by providing the sec- 40: ond section with `channel-like guidesxreceiving thefrst section. z
